Work Step by Step
(a) Number of protons and neutrons in the nucleus
Protons = 7
Neutrons = 7
(b) Atomic number (Z)
The atomic number is equal to the number of protons.
Z=7
(c) Mass number (A)
Mass number = protons + neutrons
A=7+7=14
(d) Number of electrons in a neutral atom
A neutral atom has electrons = protons.
Electrons = 7
(e) Element symbol
Atomic number 7 corresponds to Nitrogen (N).
Isotope notation: $^{14}_7N$ or Nitrogen-14
